swamper grooving pattern (1 Viewer)

[69LC]

While watching movies in the living room yesterday, I snuggled up with a swamper(38.5") and started working with a bunch of sharpies. I don't have my groover yet, so I can change whatever I want. For whatever reason, my wife wants me to take it back to the garage when I go to work this afternoon…

So what do you all think? My goal was to balance the angles of the tread block faces and open up the center just enough.

I don't know about the why's of grooving without having an understanding of the advantages of angles of the grooves. But I will suggest having the tires cut with sipping. This does have huge advantages.
I don't think that cutting a straight line through the center blocks like that unless you are going for a real mud advantage, but you'll affect your lateral stability, at least the way I see it.

I grooved and sipped my swampers and the fronts chunked out really bad. I'll put up a pic today if I get a chance. it could have been a combo of doing both.

BionicCruiser, Were you at CM05? Your truck looks familiar.

I grooved my TSLs and it made an unbelievable difference on the rocks. They wrap better, grip better and just work much, much better.

Siping works on the road on ice. It won't do much of anything on the rocks.

Gumby, I was at Rocks and Valleys off road park with my buddy and his samurai buggy this fall. He has worn 38.5 SXs and also has them cut. I was super impressed with how they did exactly as you described. I will have to pony up for some inner air locks to go to single digit pressure though. Mine are 16.5s. The price was right.

I think I was. I've been to many CM's. I also made it into Henry's calendar, probably 2006 from the CM05.


now onto the sipping pics, here's what I did. first pic was a rear tire (good shot of how it was done), and the second is a close up of a front that chunked out. I agree that the sipping is better for icy roads.

so I think that the diagonal grooves you have are good. I did mine to the center of the far side instead of the corners like you drew out. just don't go too crazy and leave smaller blocks. that's why mine chunked IMO. grooves and sipes too close together.

I just did a little to my old bias ply Buckshots and was pretty surprised the improvement it made...

Nice pics! Thank you.

I was at CM05 with luke porter and his green hzj61. I have dreamed of going back since.

Thank you guys for the feedback.

We get a fair bit of snow along with our mud here and I want to have all around decent trail tires. I'm hoping to pick up a set of nearly new hummer tires for driving to work and save the swampers for the trail.

I sip'd the middle ones about 1/4" apart and made a big difference on the rocks.

This is how mine were grooved, similar to Gumby and they worked very well

Cutting the center of the tread blocks lets the tire flex around rocks, cutting every other tread block on the outside gives the side walls some flex but keeps them rigid enough to climb with.

For what it's worth I ran below 10psi most of the time with no bead locks. occasionally I'd have to add air on the trail but most times not. If I got another set of Swampers I'd groove them exactly the same way.

Hi all,

Great thread, thanks for all the info guys!

Dan (aka Rusty_TLC) what tool did you use to grove your TSLs?
